Fuel Processing Technology · 2026

Combining densification with torrefaction can substantially improve fuel properties, including energy content, grindability, and hydrophobicity, enabling torrefied pellets to replace coal in pulverized fuel boilers. This study investigates biomass pellet torrefaction using an innovative vibrating torrefaction system developed in this work, representing the first pilot-scale technical assessment of Thai biomass feedstocks. The objectives were to evaluate torrefied pellet properties and assess production costs. Rubber wood waste pellets (RWP) and corn waste pellets (CWP) were torrefied at 220–300 °C with residence times of 16 and 30 mins. The results indicate that increasing torrefaction severity enhanced fuel quality, with the heating value (HHV) reaching 22.4 MJ/kg, approximately 20% higher than raw pellets, along with improved grindability and moisture resistance. These improvements were accompanied by reductions in mass and energy yields, indicating that heating value alone is insufficient to assess process performance and that energy yield must also be considered. Specific electricity consumption ranged from 624 to 1161 kWh/ton of product, depending on torrefaction severity and mass yield. A preliminary cost analysis, accounting for capital investment, feedstock cost and electricity consumption, estimated production costs of 8000–11,000 THB/ton of torrefied pellets.

ACS Environmental Au · 2026

Abstract This study employed both qualitative and quantitative approaches to examine Supermarket Food Waste (SFW) and Packaging (SPK) generations, as well as current management practices implemented by supermarkets and public agencies, using Bangkok, Thailand as a case study. Two supermarket chains provided SFW data and participated in interviews, along with three agencies from the Bangkok Metropolitan Administration (BMA) and four private waste processors were interviewed to explore the current SFW management practices. Carbon Footprint (CF) and Life Cycle Cost (LCC) analyses were also conducted to support the development of policy recommendations for sustainable SFW management. Results indicated that fruits and vegetables and plastics constituted the largest portion of SFW and SPK, accounting for 92.09% and 80.20% respectively, with a packaging-to-food weight ratio of 0.09 kg SPK/kg SFW. Thematic analysis revealed that strong public-private partnerships between supermarket parent companies and public agencies significantly influenced operational efforts, leading to successful SFW management. Based on these findings, policy recommendations were developed across three dimensions: environmental, economic, and policy; tailored to supermarkets and public agencies to support sustainable SFW management.

This study analyzed categories and quantity SFW generation from a supermarket in Thailand. Supermarket food waste (SFW) from a supermarket in Bangkok was collected, classified, and analyzed. This study assessed the carbon footprint (CF) and life cycle cost (LCC) of four management scenarios: landfilling, energy-recovery incineration, and biochar conversions for utilization as alternative fuel and soil amendment—using a functional unit of one tonne of generated SFW. CF was calculated using the IPCC 2013 LCIA method, while LCC included investment, operation, and maintenance costs. The results revealed that Fruits and vegetables (67.91%) were predominant in SFW, highlighting its suitability for organic waste conversion, while plastics (78.69%) constituted the majority of supermarket packaging waste (SPW), highlighting potential for segregation and material recovery. Landfilling imposed the highest environmental and economic burdens, with CF of 622.31 kgCO 2 eq and LCC of 66.64 USD. Energy-recovery incineration produced CF of 273.57 kgCO 2 eq and LCC benefit of -25.27 USD. Biochar conversion as alternative fuel resulted in avoided CF of -57.53 kgCO 2 eq and LCC of 33.51 USD, while biochar as soil amendment provided the greatest avoided CF of -560.33 kgCO 2 eq but incurred LCC of 54.71 USD. These results highlight the environmental benefits of SFW biochar conversion, particularly for soil amendment application, though economic performance must be improved to enhance competitiveness. • Fruits and vegetables was the majority among supermarket food waste (67.91%). • Energy-recovery incineration offered financial benefits. • SFW biochar utilizations offered environmental benefits.

This study proposes a novel two-phase model framework for designing sustainable biomass supply chains of Community-Scale Biomass Power Plants (CSBPPs) by optimization based on geospatial-based Multi-criteria Decision Making (MCDM), the Analytic Hierarchy Process (AHP) method and the Location–Allocation Model. Phase I involved land suitability criteria prioritization and suitable land area analysis. The location–allocation model was the main tool used in Phase II to identify optimal locations, followed by the analysis of the levelized cost of electricity (LCOE). The model optimized site location based on the availability (remaining) of local crop residues, electricity demand, road networks and other key criteria for power plant development, such as the location of substations and the location of existing power plants. The results show that the estimated total remaining crop residue potential in the EEC region was 2403 kt/year, which can generate approximately 34,156 TJ. The location–allocation model identified the top five locations for CSBPPs. The total required installed capacity of these five locations was approximately 100.23 MW in order to serve the district energy demand by the residential sector of 793.82 million (kWh/year). Assuming direct combustion-steam turbine technology with an installed capacity of 6–10 MW, the average LCOE was found to be in a range of $0.076 to $0.081 USD/kWh.

Energies · 2025

Community-scale biomass power plants (CSBPPs) offer a decentralized approach for electricity generation by utilizing locally available biomass while delivering socioeconomic benefits. Site selection plays a critical role in the success of CSBPPs and requires the consideration of diverse spatial and non-spatial factors. This study presents a spatial decision-support tool for identifying suitable CSBPP sites in Thailand’s Eastern Economic Corridor (EEC), which comprises the Chachoengsao, Chonburi, and Rayong provinces. A geoprocessing workflow integrating Geographic Information Systems (GISs), Multi-Criteria Decision-Making (MCDM), and the Analytic Hierarchy Process (AHP) was developed using ModelBuilder tools in ArcGIS Pro (version 3.0.2). Thirteen sub-criteria related to geographical, infrastructural, and socioeconomic–cultural dimensions, along with exclusion zones, were evaluated by 15 experts from diverse stakeholder groups. Biomass availability from five major economic crops was combined with other spatial data layers, incorporating expert-assigned weights and suitability scores. The findings indicated a remaining biomass energy potential was 34,156 TJ, with sugarcane residues contributing over 80%. Approximately 20% of the EEC area (about 0.262 million hectares) was classified as highly suitable for CSBPP development, revealing several viable site options. The proposed model offers a flexible and replicable framework for regional biomass planning and can be adapted to other locations by adjusting the criteria and integrating optimization techniques.

Abstract This research investigates the influence of torrefaction and catalytic pyrolysis of raw corn waste (RCW) to upgrade the quality of bio-oil. RCW was torrefied at 280°C for 16 mins to produce torrefied corn waste (TCW). Natural basic oxides (CaO and MgO) catalysts were selected because of inexpensive and high catalytic performance. Pyrolysis experiments were conducted in a bench-scaled bubbling fluidized bed reactor at 500°C. The effects of torrefaction and the presence of a catalyst on the pyrolysis product both yield and composition were investigated. The results from non-catalytic pyrolysis revealed that TCW pyrolysis gave 15 wt.% lower in oil yield, and about 6.8 wt.% lower in gas yield but the char yield was approximately 22 wt.% higher compared to the pyrolysis of RCW. Considering the effect of catalyst, the yield of bio-oil reduced slightly, while the yield of char and gas increased compared to non-catalytic pyrolysis for both RCW and TCW. The bio-oil composition derived from TCW pyrolysis contained more phenolic and aromatic compounds and significantly lower oxygenated compounds when compared to that of RCW pyrolysis. Moreover, with the presence of the catalysts, the bio-oil composition and HHVs of bio-oil was also improved.

International Journal of Energy for a Clean Environment · 2022

The present article aims to review the influence of various biomass pretreatments on the production of bio-based transportation fuel and chemicals via pyrolysis and hydrodeoxygenation (HDO). The article includes the influence of different thermochemical pretreatments such as dry torrefaction (DT), wet torrefaction (WT), steam explosion treatment (SET), hot water extraction (HWE), acid treatment (ACT), and alkali treatment (AKT) on bio-oil yield and bio-oil properties. HDO primarily includes dehydration, hydrogenolysis, decarbonylation, and hydrogenation. HDO can be classified based on stages (single and two-stage HDO), reaction pressure (high and low), and hydrogen presence (ex situ and in situ). The recent developments, advantages, and drawbacks associated with different types of HDO processes have been included. The article includes recent studies on designing various catalysts based on HDO conversion of different bio-oil compositions or selective model compounds to targeted bio-based products. The various biomass pretreatments impact the concentration of certain families of organic compounds present in bio-oil. Hence, the present review article also includes recommendations of specific biomass pretreatments for various HDO catalysts designed for selective model compounds or different bio-oil compositions. Few praiseworthy techno-economic analysis (TEA) studies on the influence of different biomass pretreatments on the minimum selling price (MSP) of bio-based products obtained at various production stages have been discussed.
